If the sponsor is unsure of the exact date they became a naturalized citizen, is it ok to be an estimate that's within about a year's time? The sponsor does have a Certificate of Canadian Citizenship card, however it only has the date the card was issued. We've also tried calling CIC however they weren't able to provide that information to us and suggested to apply for a citizenship certificate, which would take another 10 months.
Is there any other way to find out the information or would an estimate, within a year's range, be sufficient for the application>
